WHISTLE-PIPE.`

SPECIFICATION forming part of Letters Patent No.` 611,028, datedSeptember 20, 1898. Application filed September 23,1897. Serial No.652,712. (No model.)

To all whom it .may concern:

Be it known that I, JOSEPH BRYSCH, a subject of the Emperor of Germany,and'a resident of Skronskau, in the district of Kostellitz, UpperSilesia, Empire of Germany, have invented certain new and usefulImprovements'in Vhistle-Iipes, Flutes, and the Like, of which thefollowing is a full, clear,and exact description.

The present invention consists of an improvement in whistle-pipes,flutes, and the like.

Instead of forming the various notes by means of holes in the pipe orvalves, as hitherto, the various tones are produced by means of a pistonor plunger movable in the pipe and by which moans the length of thelatter is varied, and in order to render the present specification moreeasily intelligible reference is had to the accompanying drawing, whichlshows alongitudinal section through a whistle-pipe constructedaccording to the present invention.

The pipe consists, mainly, of two parts A and B, the former comprisingthe tube or pipe a, having the plug c and vent I, as usual, and thelatter consisting of the rod (j, having piston or plunger f and handle7L. The end of the pipe a is closed by a disk or gland e, into which thepiston-rod fits air-tight. The various tones are produced by shorteningthe length of the pipe by means of the piston f.' The rod g of thelatter is provided with a series of notches 'i 2 3 4, dsc., by means ofwhich the various tones may be determined.

Thus if it is required to sound do the first notch will be employed, thepiston being pushed into the pipe as far as the same. If mi is required,the piston will be pushed into the pipe up to notch No. 3, and so on.

In playing the instrument the pipe is held with the left hand, theright-hand thumb-nail is placed on the piston-rod over the notches andinserted into the notch corresponding to the note which is to besounded, and the rod is pushed into the pipe up to the thumbnail by oneof the other fingers of the right hand, which should bc inserted intothe handle h. A

It will only be necessary for beginners to use the not-ches, asexperienced players will be able to sound the right note without the aidof the notches.

I claim as my invention- In a whistle-pipe having a piston movabletherein and a piston-rod to operate same, the combination of a series ofnotches on the said rod, corresponding to the notes of the tonic` scale,into which notches the linger-nail of the player may be inserted toilxthc position of the piston for a certain note substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
